Fine extrusion chamber.Specifically, the side of optical fiber gland 52 is hinged by pin shaft and fibre clip pedestal 51, so that optical fiber gland 52 can
It is overturn around fibre clip pedestal 51.
Optical fiber is put into V-groove 511, when the overturning of optical fiber gland 52 is bonded to its bottom with fibre clip pedestal 51, light
The bottom of fine gland 52 applies pressure on optical fiber top, meanwhile, the two sidewalls of V-groove 511 provide the left and right sides of optical fiber oblique
It upwards pressure, optical fiber realizes firm clamp under the collective effect of V-groove 511 and optical fiber gland 52.This kind of clamping side
Formula is similar to the clamping of three-pawl type, of less demanding to the precision of fiber size, can also be with even if the circularity of optical fiber is not accurate enough
The clamping of optical fiber is realized well, and then ensures the precision of performance test.Meanwhile the second magnetism is provided on optical fiber gland 52
Part is provided with third magnetic part on fibre clip pedestal 51, and optical fiber gland 52 turns to when being bonded with fibre clip pedestal 51, third magnetic
Property part and the second magnetic part magnetic attraction.Second magnetic part and third magnetic part can be the combination of magnet and iron core, can also be with
It is all magnet.The position on optical fiber gland 52 is arranged in preferably far from hinged side, convenient for the more firm of magnetic in magnet.
Further, the bottom of optical fiber gland 52 is provided with flexible glue, and optical fiber gland 52 is turned to be pasted with fibre clip pedestal 51
When conjunction, extrusion chamber is collectively formed in the two sidewalls of flexible glue and V-groove 511.Flexible glue is to be formed with plastics by injection molding, and flexible glue is deformable
And it is anti-skidding, flexible glue squeezes optical fiber, on the one hand optical fiber is protected to be not damaged, on the other hand can make up optical fiber by the deformation of flexible glue
Dimensional discrepancy, further ensure the effect of clamping.
Preferably, positioning convex strip 512 has been arranged radially on fibre clip pedestal 51, the bottom of optical fiber gland 52 is provided with and determines
The chimeric positioning groove 522 of position raised line 512.When optical fiber gland 52, which is turned to, to be close to fibre clip pedestal 51, positioning convex strip 512
It is nested with positioning groove 522, positioning groove 522 realizes guide-localization, it is ensured that the position of 52 closing lid of optical fiber gland is accurate.Together
When, when optical fiber, which receives, to be pullled, optical fiber applies axial frictional force, optical fiber gland to optical fiber gland 52 and fibre clip pedestal 51
52 will not move axially under the limitation of positioning groove 522 between fibre clip pedestal 51, it is ensured that the effect of fiber gripper
Fruit.
Further preferably, optical fiber gland 52 is being formed with the clicking section for protruding from the fibre clip pedestal 51 far from hinged side
521, facilitate operator's rotating opening optical fiber gland 52.
In order to facilitate the installation of, fibre clip pedestal 51 is provided with the mounting portion 513 positioned at 52 front end of optical fiber gland, mounting portion
513 are provided with mounting hole, and threaded hole is provided on tool part, and optical fiber clamping structure 50 can be fixedly mounted on tool part by screw
On.
Meanwhile fibre clip pedestal 51 is additionally provided with the guide part 514 between mounting portion 513 and optical fiber gland 52, leads

On sliding block 71.The one side edge of collection box 100 is upwardly formed mounting rack, for blade cleaning module 90 to be fixedly mounted.
Each transmission parts structure in the optical fiber fiber stripping mechanism is simple, steady reliable, is spatially arranged rationally.
Preferably, when the first blade 811 and the second blade 821 are moved towards to minimum range, the first blade 811 and second
The distance between blade 821 is greater than the core diameter of optical fiber and is less than the cladding diameter of optical fiber, and blade is avoided to be cut into optical fiber
Core, and optical fiber is damaged.
Meanwhile hairbrush 92 includes support shaft and hair root, hair root is attached in support shaft in divergent shape, and circular hair root is formed
When the outer diameter of hairbrush 92, the first knife rest 81 and the second knife rest 82 are moved to maximum distance backwards, the first blade 811 and the second blade
The distance between 821 are greater than the diameter of support shaft, avoid support shaft and blade hit, and then damage blade；Also, the first knife rest
81 and second the distance between knife rest 82 be set smaller than the whole outer diameter of hairbrush 92.Hairbrush 92 is softer, is easily deformed, hairbrush 92
When whole outer diameter is larger, be conducive to improve cleaning effect.
In addition, the quantity of fiber stripping cylinder 80 is two and is arranged in concordant, in rotation axis 91 in double optical fiber fiber strippings mechanism
The quantity of hairbrush 92 is arranged accordingly to two.
Other function module in the equipment does not carry out detailed record in the present specification, does not represent the equipment
Specific structure insufficient disclosure, the other function module that do not record have been all made of structure and principle commonly used in the art, should manage
Solution is by as it is known to those skilled in the art that does not influence the implementation of equipment entirety.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned embodiment party
Formula within the scope of knowledge possessed by those of ordinary skill in the art can also be before not departing from present inventive concept
